Description
Technical field
The utility model relates to communication equipment field, especially a kind of optical connector of replaceable smooth wire jumper.
Background technology
A kind of optical connector is arranged on the market; This optical connector comprises housing unit; Housing unit comprises and all is tubular and coaxial inner housing that is assembled together and shell body; Said inner housing is preset with the light wire jumper, and in order to guarantee the sealing of this electric connector afterbody, said smooth wire jumper is located in the inner housing by non-removable when dispatching from the factory.What this optical connector was often used in communication system is in the base station; Yet connecting head dummy RRU (radio frequency remoto module), the waterproof in the base station needs on the light wire jumper, water joint to be set with the light wire jumper; The chamber type RRU that safeguards in the base station does not need water joint with the light jumper zone; Because the light wire jumper in the inner housing of above-mentioned optical connector is preset and non-removable; Therefore can't realize safeguarding that chamber type RRU is connected the conversion of head dummy RRU with the light wire jumper with the light wire jumper with waterproof, increase the failure risk of subscriber equipment, be not easy to user's unified management.
Summary of the invention
The purpose of the utility model is to provide a kind of optical connector of replaceable smooth wire jumper, can not change the problem of light wire jumper to solve existing optical connector.
In order to address the above problem; The optical connector of the replaceable smooth wire jumper of the utility model adopts following technical scheme: the optical connector of replaceable smooth wire jumper; Comprise inside and outside housing, turn edge in the tail end of said shell body is provided with that the leading flank that turns edge in said is in the past backward gradually to inclined-plane that the center line of shell body is drawn close; Said inner housing is from removable being plugged in the shell body of front end of shell body; Shell body turn edge within it and inner housing between be provided with the flexible fastening cover, said flexible fastening cover comprises the matrix of C shape, the outer peripheral face of said matrix is provided with shoulder; Said shoulder is inlaid in along the fore-and-aft direction activity in the annular groove on the internal face of being located at shell body and between the rear side wall of the trailing flank of shoulder and annular groove has the locking spacing; The rear end of matrix has pre-large post-small conical section, the retaining edge of turning in the rear end of said conical section has, said retaining edge with said in the leading flank that turns edge be slidingly matched; The coaxial elasticity envelope line cover that is provided with in the flexible fastening cover, said elasticity envelope line is placed in its jacket wall and is provided with the harmomegathus seam that extends along fore-and-aft direction.
The trailing flank on said retaining edge for said in the medial surface that the turns edge inclined-plane of fitting.
The rear end that said flexible fastening is placed in its taper hole section offers the harmomegathus mouth and forms the bullet pawl in the both sides of said harmomegathus mouth.
Because the optical connector of the replaceable smooth wire jumper of the utility model turns edge in the tail end of its shell body is provided with; In the leading flank that turns edge in the past backward gradually to inclined-plane that the center line of shell body is drawn close; And inner housing is from removable being plugged in the shell body of front end of shell body; The rear end of inner housing and said in be provided with said flexible fastening cover and elasticity envelope line cover between turning edge, the rear end face of flexible fastening cover with in the leading flank that turns edge be slidingly matched; Therefore; When wiring, can first said inner housing be overlapped from shell body, to unload with elasticity envelope line and get; The light wire jumper of correspondence is passed shell body from the rear end of shell body; Elasticity is sealed the line cuff in the outside of shell body then and be located on the cable of light wire jumper, because elasticity envelope line tackling has said harmomegathus seam, in this process; Can elasticity be sealed the line cover breaks into two with one's hands the cable of light wire jumper is filled in elasticity envelope line cover; At last the light jumper terminal is introduced inner housing and inner housing is inserted shell body together with people's elasticity envelope line cover get final product, can be in the process that shell body moves forward with respect to inner housing during use turning edge in through shell body holds out against the flexible fastening cover and seals that line overlaps and the line of light wire jumper, the tail end of can body to compress elasticity; The optical connector that this shows the utility model can be changed dissimilar light wire jumpers as required at any time, has solved the problem that existing optical connector can not be changed the light wire jumper.
